BIO 1_Chromosomes & Reproduction

The n number of human chromosomes is

• 12

• 23

• 92

• 46

The 2n number of human chromosomes is:

• 23

• 46

• 92

• 12

Each identical side of a chromosome is the 

• centromere
• chromatin
• centriole
• chromatid

When DNA is in its less coiled, "relaxed," state, between cell divisions, it is called

• autosomes
• chromatid
• chromatin
• centromere

Autosomes are

• chromosomes found in autotrophs, only
• chromosomes that automatically correct all errors in the DNA
• chromosomes that determine traits other than sex
• chromosomes that determine the sex of the individual

The structure that holds two chromosomes together until they separate for cell division is the

• chromatid
• chromatin
• centromere
• cytoplasm

Cells that contain two sets of chromosomes (example: 2n = 46) are:

• Gametes

• Haploid

• Diploid

• Sex Cells

Chromosomes contain genetic information in the form of:

• DNA

• RNA

• Centromeres

• Somatic cells

Sister chromatids are held together by a

• histone core

• chromatin

• nucleosome

• centromere

Gametes that contain one set of chromosomes (example: n = 23) are called

• diploid

• autosomes

• haploid

• somatic cells
